Never operate a bare bucket – The baseedge is an integral part of the bucket anddirectly affects its structural strength. Replacing the base edge generally removes machines from productive useduring the repair period. Extension of base edge life through wear plates is aneconomic method of increasing machineup time. If the application does not requirebucket teeth or teeth with bolt-on edgesegments, then use flat bolt-on or weld-onhalf-arrow edges.
Replace worn base edges – Base edgesshould be replaced before they wear thinenough to fail. A failure means unscheduleddowntime and a chance for structuralbucket damage. If possible, use eitherCorner Guard System base edges orCaterpillar Rock Bucket edges with pre-drilled bolt holes. Both permit use of all available options.
Rotate bucket tips and bolt-on edgesegments – Rotate tips from ends to thecenter and vice versa, also turning themover. Rotating and turning tips will extendwear life, distribute wear, and maintain tipsharpness. Rotating end segments towardthe center at turn time will distribute wearamong segments.
Run bolt-on edges, segments, and tipsto their full service life but not beyond –Exceeding wear life could cause wear tobucket structural members and result inhigher repair costs.
Maintain the bucket positioner inproper adjustment – This will keepthe bucket level to the ground andhelp you eliminate uneven wear onthe bottom. Maintaining properbucket positioning will generallyplace tips at the angle for optimumpenetration.
Check the lubrication daily on the bucket linkage pins – On machines not equipped withsealed linkage pins, considerinstalling them. They will extendlubrication intervals and reducemaintenance time. See lubricationinstructions in your machinemaintenance guide.
Minimize bucket contact with the ground – Lower the bucket to the ground only when you areready to enter the stock-pile. Unnecessary contacts with theground wear the bucket bottom andincrease GET consumption.

Abrasion-Resistant Material
Center EdgeEnd Bit
When penetration is not a problem, such as clean-up work or stockpiling, use the Corner Guard cutting edges. This system:• increases base edge life up to 5 times over unprotected base edge• is quick and easy to replace• increases bucket capacity• provides smooth floor maintenance capability• is made from DH-2 steel alloy, through hardened to 430-520 Brinell.
Standard cutting edges can be “propellered” to present a second wear life. Available for the full range of Wheel Loader (except 990-994).
Heavy Duty cutting edges are also reversible. This thicker option provides at least 50%more wear material and a better cost per hour. Available for 950B/E/F, 966C/D/E/F,980C/F/G.
The Abrasion Resistant Material (ARM) cutting edges are available for Corner GuardSystem fitting General Purpose and Multi-Purpose buckets. Very hard abrasion resistantparticles have been added to protect critical wear areas (under the leading edge, in front ofbolt heads, and under the bucket’s front corners).
Recommended for low to moderate impact applications, it is ideal where sand, gravel and other abrasive materials create high wear rates.
These edges are not reversible but will give you three to five times the wear life of standardbolt-on cutting edges and are very cost effective in stockpile application. Available for thefull range of Cat loader (except 990-994).
Corner Guard Bolt-on Cutting Edges
Two-Bolt Corner Guard
Corner Protectors for Bolt-on Cutting Edges
The corner protectors are designed to protect the bucket corners from wear when bolt-oncutting edges are used. This will ensure that bucket corners can accept bolt-on adapterswhen necessary. They will also provide a sharper edge than the bucket corner. This willresult in better penetration in stockpile, bank loading, and light excavation applications withcorner guard system buckets.
Bolt-on Cutting Edges for Rock BucketsUsed across the entire rock bucket base edge, bolt-on cutting edges:• can extend the base edge life up to five times• maintain smooth, clean work surface• increase bucket capacity• are reversible to provide a second wear life• are ideal for abrasive conditions were penetration is not a problem• are made from DH-2 steel alloy, through hardened to 430-520 Brinell.
Heavy Duty options are thicker for extended wear life and lower cost per hour.Available for 980 - 992
* ARM edges and end bits have the same Length and Thickness as the standard edges and end bits.

Key Benefits – Cat Heavy Duty Quarry Buckets offer superiorprotection, durability and performance. Specifically designed forquarry, aggregates and mining operations in high impact and/orhigh abrasion applications, these buckets are factory-modified withadditional protection.
Heavy-duty Cat GET components are designed to reduce downtime and bucket-related operating cost to help you get the mostfrom your machines. Each protection item and component wascarefully chosen in response to customer requests for a bucket thatdelivers maximum strength, durability and wear life in highimpact/high abrasion conditions.
1 Liner** – Adds strength and extends overall bucket life. The base edge is raised to match the liner’s height and provide a smooth working surface.
2 Inner Side Wear Plate – One piece inner side wear platematches thickness of outer upper side wear plate. Provides protection to lower half of inner side plate.
3 Heavy Duty Adapters 992G (Heavy Duty Quarry Bucketuses Standard J700 Adapters) – Interior adapters feature newshouldered design which provides greater strength, protection and wear life. Bottom strap thickness is matched to the thickness of the Heavy Duty Half-Arrow Segment for smoother material flow.
4 Three Heavy Duty Tip Options offer different combination ofstrength, wear life and penetration to best fit your job needs:• Heavy Duty Long Tip• Heavy Duty Abrasion Tip• Heavy Duty Long Life Tip• Heavy Duty Penetration Tip
* The Heavy Duty Quarry Bucket should only be used in material densities of 1.6 t/m3 or less due to increased bucket weight.
** All Heavy Duty Quarry Bucket wear plates options including liner, can be purchased from Cat for placement on bucket rebuilds.

7 Dual Sidebar Protectors – Sidebars are drilled to accept dual sidebar protectors. Cat Sidebar Protectors can be stacked to cover wear patterns that extend above a single protector.Single or dual sidebar protectors can be used to match the wearconditions of the application.
8 Outer Upper Side Wear Plate* – Upper side wear plates combat the wear that occurs on bucket side plates in highimpact/abrasion conditions. Because wear on the upper areas of the bucket is less severe, these plates are thinner than thelower side wear plates to save weight.
9 Outer Lower Side Wear Plate* – Lower side wear plates are thicker than the upper side wear plates. These thicker plateshandle the greater wear which occurs on the lower quarter of the bucket sides in tough quarry, aggregates and miningoperations.
* All Heavy Duty Quarry Bucket wear plates options including liner, can be purchased fromCat for placement on bucket rebuilds.
10 Outer Skid Plates* – Skid plates on the outer bottom areas of the bucket shield high wear areas at and just behind thebucket’s corners. They also add corner strength. Skid platesextend past the outside of the bucket side plates to protect the side plate welds.
11 Base Edge Wear Plates* – Wear plates offer enhancedprotection to the base edge. Bolt holes accept bolt-on wearplates for complete edge protection and extended base edgelife. Base edge wear plates cover the bottom area of the baseedge not protected by segments.
12 Heavy Duty Rear Wear Plates* – Bolt-on thicker rear wearplates extend life.
13 Hinge Bracket Wear Plates* – Weld-on wear plates protect the lower heel of the hinge bracket assembly during bucketloading for longer bracket life.

Bottom – Inspect inside and undersidelooking for cracks in bottom either alongwelds or through plates. Cracks hereindicate structural failure. Major repairsmay be needed. Are there areas of extremewear? Bottom may be weakened by wearand subject to early failure.
Replace worn edges – Edges shouldalways be replaced before the bucket isdamaged by wear or weakened throughloss of edge support.
Replace worn side-cutters – Side-cuttersshould be replaced if they no longerprotect the side-plates of the bucket.Always check for loose bolts and maintainproper torque to avoid loss of side-cutter.
Rotate and turn tips – A blunt tip reducesloading efficiency. Caterpillar’s tips areself-sharpening for efficient penetrationthroughout their service life. Tips seldomwear evenly, usually the ones near thebucket corners wear fastest. Byperiodically rotating outside tips to thecenter and also turning the tips over, tip life can be increased up to 50%. This method “evens out” tip wear. A bucket that is regularly loaded at anangle into the material will show unevenwear on the leading side. Rotating andturning tips or a change in loadingdirection will help equalize your tip wear.
Replace worn wear plates – Look forsevere wear near the rear of plates. If theyare severely worn, cracks are likely todevelop around them. Wear plates are notpart of the basic bucket structure, but areused to protect the structure. They shouldalways be replaced before they wearthrough. If the basic structure is weakenedby wear, it may be necessary to rebuildyour bucket before installing new plates. It is always easier and less costly to installor replace wear plates before your bucketsuffers damage.
Bucket Maintenance Tips How to select the right bucket for the job
Utility Standard (SU). – Demolition and construction bucket handles bricks and broken concrete, as well as trench filling, floor leveling and bank finishing.
Utility Light (LU). Low cost earthmoving bucket for floor, bank and ditch finishing.
Excavation/Trenching (X). – Digs and loads soft to medium materials such as clay. Features weld on tip adapters, hardened cutting edge and side bars.
Extreme Excavation/Trenching (EX). – Digs and loads compact/abrasivematerials like earth/rock, sand/clay, sand/gravel, coal, chalk and low abrasionores. Features bigger ground engaging tools, plus abrasion resistant steel for allwear parts.
Rock (Classical/Standard). – Digs and loads mixed earth/rock soils containing high percentage of rock or other abrasive materials. Features V-spade cutting edge, thicker base and wear surfaces.
Rock Loading (RL)*. – Loads large blocks of rock and other abrasive materials. Features longer floor plate and increased side bar curvature for better stability under load.
Block Handling (BH)*. – Handles pre-shaped blocks of marble, granite, in quarries. Features increased tip radius, deep cut side bars for long floor platform.
Skeleton Light (SL)*. – For soft and humid soils or where separation ofmaterials, e.g., branches, peatmoss, is required.
Skeleton Heavy Duty (SH)*. – As S.L., but for more demanding separation work such as sorting rock from sand or gravel on demolition sites.
Ditch Cleaning (DC). – Wide, light bucket used mainly with long reach configurations to clean water beds and banks.
Trapezoidal (T)*. – To prepare and maintain small irrigation ditches.Features angled sides to shape ditch banks in one operation.
Bucket choice is a key to success, and it depends mainly on the material to be worked. Is it compacted or fragmented? How abrasive? Does it require digging, handling orseparating? These variables dictate bucket design, choice of steel, component thickness and accessories. You can be sure to find the right combination in the Cat excavator bucket range.
* Bucket available on a “Made As Ordered” (MAO) basis.See you Cat dealer for further details.

Bolt-on Adapters for Front End Loaders
The Corner Guard System uses two strap bolt-on adapters with fitted tips.
One-Bolt Corner Adapter• Protects bucket corner for longer base edge life.• Easy to install, remove and replace.
Two-Bolt Corner Adapter• Keeps adapter securely attached. Prevents shifting.• Eliminates stress and associated breakage of inner ear of one-bolt design• Keeps tip aligned during entire life• Easy retrofit. Converts old buckets with new corners and simple
welding process.
Center Bolt-on Two-Strap Adapter• For general loader applications when you don’t need a smooth
work surface.• Provides good base edge protection.• Easy to install, remove and replace.
Left hand and right hand positions arebased on a view from the cab.
Unitooth
• Tip and adapter are one integrated piece for easy installation andlower initial cost
• Improved penetration where breakage is not a problem• Recommended for nonabrasive materials
The offset concept available for all adaptersHow fast and easily a tooth digs depends on its offset, its position with respect to the base edge. Offset is measured from the base edge planed to the front of the tip.
The greater the offset, the more aggressively the tooth digs.
How to find the tip family ?Place a tape measure across the back of the tip at midpoint of the side walls.Example: 3.0" (76.2 mm) measure is J300 family
3.5" (88.9 mm) measure is J350 family5.5" (139.7 mm) measure is J550 family

Mechanically Attached Wear Plate Systems
The Mechanically Attached Wear Plate System provides a hammerless means of installation and removal. They are capable ofprotecting wear areas previously unprotected or on areas previously protected by weld-on or bolt-on wear plates. Skeletal MAWPS usesthe same Series 20 base and retainer as the regular MAWPS, but has a modified skeletal plate that fits on the base. The Skeletal MAWPSwear plate is skeletal in form so it traps material in the plate and between the plates, adding an extra layer of protection.
• Mechanical, hammerless installation - The system consists of a through-hardened DH-2 wearplate which slides onto a weld-on base plate and is held in place with a patented compressionretainer.
• Reduced downtime and maintenance - worn wear plates can be replaced quickly and easilyusing a common prybar or MAWPS removal tool, 160-5119. Wear plates can be replaced withouthammering or welding.
• Extended Wear - Patented compression retainer is positioned low in the base plate allowing agreater percentage of the wear plate to be worn away before replacement. The base plate is notsubject to wear under normal conditions since it is entirely covered by the wear plate.
• Flexible Application - The weld-on base plate can be welded on virtually any flat or moderatelycurved surface. The system is designed to take loads from any direction so the orientation of theweld plate to the direction of the load is inconsequential.

The high chrome alloy “white iron” is brazed to a mild steel backing plate which can be plug-weldedwith an E7018 3/32” (or similar) stick electrode to a bucket, dozer moldboard, or anywhere quickinstallation, low cost, abrasion protection is desired.
This product is designed to add long wear life in highly abrasive applications. It has a hardness rating ofRc 60-65 and offers lower cost protection than “hardfacing”. • quick installation• versatility• low cost• protected welds and steel base
Inspect used pins for damage. Unless theyare obviously bent or severely damaged,there is no need to replace them. On grooved pins, damage in the groove ismore critical because the pin is thinner inthis area. Slightly damaged groove wallsshould not be cause for rejecting a pin.However, as the walls flatten out, the advantage of the groove becomes less.
For maximum security, retainer assembliesshould not be reused. However, in mostapplications, retainer assemblies canprobably be reused at least twice. This isespecially true when used on grooved pins.Do not attempt to straighten or reuse aretainer assembly that has been bent.
Installation adviceAlways drive pin in from thecounterbore side of adapter.
Pins for side pinned tips and adapters onbucket edges can work out of position ifimproperly installed.
When the pin and retainer assembly areremoved, drive the pin out from thecounterbore side (from machine left tomachine right). Do not use a tapered punchto remove the pin as it will cause theretainer assemblies to spread. A smallerdriver (3 mm) than the diameter of the pinshould be used to eliminate retainerassemblies damage.
Standard Retention System (J200)• Grooved pin eliminates pin walking in general applications.• Increased retainer hardness increases clamp force 35%.• Retainer holder eliminates distortion during installation.
Heavy Duty Retention SystemIn a standard retention system, the retainer is free to rotate around the pin. In some applications,abrasives can work their way between the pin and the retainer, causing wear as the retainerrotates. As a result, the retainer can lose its grip on the pin, allowing the pin to "walk" outthe retainer and causing the tip to fall off the adapter.
The Heavy Duty Retention System has a two coil retainer which• Grips the pin much tighter• Stops retainer rotation and keeps abrasives from causing pin and retainer wear• Will not spread when subjected to side loads.
Designed for easy installation:• Ivory-colored plastic holder helps align the pin and retainer during installation to assure
maximum clamping force and prevent possible retainer damage• Ivory-colored holder cues installer to use Heavy Duty Pins ONLY with
Heavy Duty Retainers• Heavy Duty Pins are chamfered on both ends to allow installation from either side,
so they can be installed easily... even on machines where space between bucket tips is tight.

Maintenance Tips
Before installing new – you should carefully inspect both the face and underside of your edge support – Check for bent or cracked areas. Look for severely worn areas that might haveweakened the support.
Tighten bolts correctly – Pay particular attention to propertightening sequence. Loose cutting edge hardware is almost certainto fail. Always use heat treated nuts and bolts in all edge and endbit installations. When installing bolts, start in the center and workout towards the ends or begin at one end and work to the other. Proper torque values are shown on page 17.
Never tighten from both ends towards the center. The reason for this is a worn or bent moldboard mightprevent proper alignment of bolts at the center of the edge.
Inspect edges and bits as part of daily routine maintenance –Check for breaks or severe cracks that could break during the next day’s operation. Tighten or replace loose or missing bolts as needed.
Replace worn cutting edges – Never start a day’s work with amotor grader whose cutting edge is worn near the edge support.
Moldboard end bits should be used for all applications –Overlays are recommended for high impact applications and whena machine is doing ditching work.
Scarifier tips should be inspected regularly and replaced beforethey wear down to the shank nose.

Always change your edges and end bits before wear reachesthe support. If wear has occurred on the support, check for burrs.Grind them off to insure that the edge or bit will fit flat against thesupport. Remove any soil that is packed between the edge or endbit and the support.
Keep your end bit and edge hardware tight at all times.Loose or missing bolts can result in failure. Use only Caterpillarhigh strength bolts and heat treated nuts with Caterpillar edges andend bits. These fasteners exceed SAE Grade 8 strength standards.
When installing new edges and end bits, the best way toinsure proper torquing is to use the “Torque – Bang-Torque”method. First torque the bolt to its specification; then tap thehead of the bolt with a hammer. This gets rid of the initialloosening which may occur. If the bolts aren’t seatedproperly, hammering can reduce torque by 40%. After hammering, retorque the bolts to spec.
Inspect bolt holes on the back side of edge and end bitsupports. Be sure there is a solid, smooth surface to support the nut. If not, it will be impossible to keep hardware tight.Repeated burning off of hardware can weaken support around the holes. Also, prolonged or repeated operation of the blade withloose hardware can cause bolt holes in the support to becomeenlarged.
Reduce speed. Speed is the enemy of your dozer GroundEngaging Tools. When a boulder or hard compact layer of materialwon’t budge, a slow and steady prying force is more desirable than high speed impact.
Operators often attempt to move a tough obstacle bybacking off and hitting it with greater momentum. This method sometimes gets the job done, but it increasesthe possibility of breaking the cutting edge and end bits anddamaging the edge support. Speed also accelerates wear onyour dozer frame, hydraulics, and the tractor drive train.
Turn your edges and replace end bits only as needed.You can lower replacement parts cost considerably by turningindividual edge sections and replacing end bits as wear limits foreach piece are reached. Downtime and labor costs involved inselectively changing, turning, or rotating dozer edges may makesuch a procedure uneconomical.
Maintenance Tips
Caterpillar offers multi-section cutting edges for easier handling,storage installation and turning. And since pieces can be replaced,switched or turned individually, you can save money by gettingmaximum wear life from each piece.
Caterpillar Cutting edges are:• Made from DH-2 rolled steel to resist breaking.• Through-hardened for maximum wear life.• Available in optional thicknesses to match edge to job.• Deep countersink for good plow bolt protection.• Extended Wear Life (EWL) Edge System.
Note: Optional cutting edges made from DH-3 steel are available for large Dozers.Ask your dealer for information.
Bulldozer Cutting Edges
While each option has specific characteristics, all versions havecommon features that help increase production and decreaseoperating cost.
• Through-hardened for maximum wear life.• DH-3 and DH-2 material are used to achieve
wear life match with edges.• Thickness in bolt hole area matches cutting edge
for long system life and provides good plow bolt head protection.
• Side extension beyond dozer sidebar protects moldboard.• Thickness in wear area designed to produce a
favorable end bit-to-cutting edge wear ratio.

Caterpillar high-strength wear plates, formed to fit the curve of the blade, are used to repair or resurface worn or damaged moldboards.
In highly abrasive or extreme impact conditions, it may be profitable to add wear plates to a new dozer before the machine is put into service.
Push plates should be installed on any dozer used to push loading scrapers. These plates are made of heat treated steel. And, like wear plates, they’re formed to fit the curve of the blade.

Wear bars provide additional blade protection in highly abrasiveapplications where short liner life has been encountered. Dozer wearbars are designed to be welded on top of the normal blade liner.This eliminates the possibility of burning through the skin of thedozer blade and generating costly repairs. Placing the wear bars ontop of a liner also results in stronger blade.
Wear bars are made from DH-2 steel alloy, through-hardened forgreater resistance and strength.

Maintenance Tips
Shanks
Inspect your ripper daily – A dailymaintenance inspection can greatly reducefailures. In the daily inspection, look for thefollowing: Worn Tips, Worn Protectors,Loose Pins, Broken Tips, Worn Shanks.
Sound operating techniques areabsolutely essential to get maximumproduction from a ripper.
Operator efficiency – Ripping is one of the toughest jobs in earthmoving. The keyto economic and effective ripping restsultimately with the operator. Therefore, you should put your best operator on theripping tractor. Much can be gained or lost,depending on his ability.
Use first gear – Ripping requiresmaximum pull. Shock loads – and ripperdamage – increase with speed. Ripping atlower speeds reduces wear, decreasesbreakage, and prolongs undercarriage life.Production can be enhanced from thisreduced downtime. Maintenance costs canrise rapidly due to wear with only a smallincrease in speed.
One piece designThe one-piece shank (no weld joint) is now available for ripper D8 size and larger. This design:• provides more strength• improves heel clearance• gives a tighter fit between the shank, tip and protector.
Straight or CurvedIf you’re operating D6 size rippers or smaller, there are two options:• Straight shanks are stronger and reach further.• Curved shanks provide better penetration by exerting
more pressure.They also lift and break material ahead of the shank and can be stored out of the way when not in use.
Repair or ConversionFor most ripper assemblies, replacement adapters and noses are available. By replacing only the portions of the assembly, repair costs can be held to a minimum. These parts can also be used on other makes of shank assemblies so you can use Cat DH-3ripper tips.
Rip downhill – Downhill ripping willenlist gravity to add to your machine pulland increase ripping ability.
Leave a cushion – Don’t take off allripped material. Leave a layer for bettertraction and less track wear.
Rip to uniform depth – This keeps theworking area level. An even cut makes foreasier loading and less wear and tear onthe hauling units.
Follow laminations – When material islaminated, rip from shallow to deep end.This pulls the tip into the ground fordeeper, more efficient penetration andimproved fracturing of material.
Break the material into a size easilyhandled by scrapers – Spacing of passes,number of passes, control of ripping depthand cross ripping determine finishedmaterial size. Thus, an experienced andcompetent operator is the only sure way todetermine depth and spacing.
Use the proper ripping angle – LargerCaterpillar Rippers feature a hydraulicallyadjustable shank angle. This allows theoperator to readily select ripper shank anglesettings forward or rearward of verticalposition. Shank angle can be changed up to33°, even while ripping. Regardless ofripper shank length or ripping depth, simplyadjust the shank angle to provide aneffective tip angle. This achieves maximumperformance throughout each ripping pass.
Use the right number of shanks – Materialdensity, rippability, machine power, andfinal size of material determine the numberof shanks that can be used. Number of shanks is largely a matter ofoperator experience and judgement. Start with one shank in the center pocketand if it is apparent that there is an excess of horse-power, go to two shanks. Do notmerely insert another shank on one of the outside pockets; remove the centershank, and install the two outside shanks. If three shanks can be used, reinsert the center shank.

Shank Protectors
To protect the lower portion of the shank and the adapter, shank protectors are availablein three different styles:• Standard design is an economical choice for light, easily ripped materials
and applications.• Sharpened design is intended for tough to rip materials. This design reduces
resistance to ripping and drawbar horsepower loss.• Extended protectors are available for highly abrasive or deep ripping applications.
All are made in DH-2 steel for maximum strength and wear resistance. They are side-pinned for easy replacement.
All ripper tips are made of through-hardened DH-3 steel.
Two types of ripper tip designs:• Centerline design should be used in most applications,
especially when wear life is a major factor. Becausethey have wear material on both sides, you can turn them overfor additional life.
• Penetration design is for hard and/or compacted materials. They have a more aggressive angle that breaksthrough the hardest surfaces and gets into the groundmore effectively.
Penetration tips should be installed with the RIB up.
For D8 and larger rippers, each tip may come in as many as three lengths: short, intermediate and long.
Always use the longest tip that wears out without breaking.If it does break, switch to the next shorter tip.
ARM intermediate tips are available. Tungsten carbideparticles form a protective shield on key wearingsurface. This helps to:• Increase tip life• Improve productivity• Reduce cost per meter of ripped material.
ARM tips are not reversible.
